4 Claims. (Cl. 257-108) My invention relates to a vat for cooling or i My invention also contemplates such other obo jects, advantages and capabilities which are inherently possessed by my invention and which willilater more fully appear. i i

While I4 have shown in the accompanying drawing a preferred `form :of` my invention,` yet I Wish it understoodthat the same is susceptible of modification and change without departing from the spirit of my invention. i

Referring to the drawing, Fig. l is a top plan `View of my liquid temperaturizing vat; Fig. 2 is a detailed vertical sectional View ofl the same; and Fig. 3 is a broken detailed verticalsectional view `of a modied form of my liquid temperaturbelow closed bottom portion I I.

`The, bottom `portion II` vhas suitable 1egsI3,

for supporting the vat on the floor or other sup- .I 8 `in`to"`which is poured the milk or other liquid to be'stored and treated therein.

jjAn agitator I9 nas a vertical rod 2u4 mounted fon the tlp` of bottomportion All"` and has a pair i :L ,of` lspaced .armsV 4I, tothe outer endsof which are attached scraper blades 42 adapted to contact lining I'I. Agitator I9, is operated by motor 30 through speed reduction member 2|.

A hollow pipe coil 22, located in the space 23 between walls I4 :and I5 winds its way spirally upwardly from the bottom of said space to the top thereof. The coil 22 is of such a diameter as to fill the space 23 laterally and contacts the inner portions of Awalls I4 and I5 leaving a spiral pathway 24.

In use, brine, ammonia or other cooling or heating liquid flows through coil 22.

In use, cover 45 is removed, `and milk, cream or other desired liquid is'poured into container I8 through the open top.` Water is introduced into well I2 `from pipe 25 leading to a source of `water supply@` i i i Motor 28 supported'adj-acent base Iltis operated and actuates pump 29 `which forces the water upwardlyfrom well I2 into spiral pathway 24, formed bythe outside of coil 22 and walls I4 and I5. When the water reachesthe top'ofpathway 24, it is directed bysprays 50 into space 5I, be-

i tween wall I5 and I6. ,The water then drops against wall It` cooling or heating the same, and

then falling into well I2 for recirculation. Over-` .thereagainst, This provides a uniform vcooling or `heating,toit/'al1 I6, The thus `temperaturized `wallwII providesblades 22 of agitator I9 with cold or` warm `contact for more eciently cooling or warming themilk or other liquid in container III.` Itl is also `tobe jnoted that `the `bottom of ,containerV I8, vliesin and contactslthe cooledor heated water inuwell I2 `for increased cooling or heating of the container contents. Y

Itis desirable that `inner wall I6 ,be`

light or thin` material` forrapid conduction of heat or cold., Wallsv I4 and t5 are made ,1 of stronger, heavier material to support thepipe coil `22, andthe forceof water in pathwaym24without buckling or collapsing.

lnanother embodimentcf myinventiorlras `shownin Fig. 3, 'I provide `a pipeline 52 leading from a water supply through Dump 53 to the top Qoffaisle 23. A pump 53 forces waterin pipeline 52 tothe top of aisle 23, where it is forced spirally downwardly in pathway 24 between coil 22 and walls I4 and I5, :and is temperaturized by contact with coil 22 to a desired cold or warm temperature. Adjacent to the bottom of pathway 24, a conduit 54 leads the temperaturized water to sprays 50 which directs it against wall I6. A return pipe 55 is provided connecting well I2 with pipeline 52.

Having thus described my invention, I claim:

1. A liquid temperaturizing vat comprising an outer shell having a bottom well portion adapted to receive water, an intermediate wall spaced spray members communicating with the top f l" said pathway, an agitator rotatablegwithinjsaid container and having members contact g the Wall thereof, and a pumping mearis ri'ivirig the water in the well upwardlynalong lsaidspiral 4 v pathway for providing cooleduwatr, saidMsiSray return members directing said cooled water against the thin wall ofthe container for cooling the contents thereof, said waterdropping back tqgsaidfwell'for recirculation jand for imparting cold to2 the lower portion of saidA ct'iijltainer.`
